The resulting infrared image revealed that Jupiter has lowered its belt. The bulk of the haze within the bight band around Jupiter’s midsection has migrated south by more than 3,700 miles (6,000 kilometers) since 2005, the researchers said.

“The change we see in the haze could be related to big changes in cloud patterns associated with last year’s planet-wide upheaval, but we need to look at more data to narrow down precisely when the changes occurred,” team member Mike Wong said in a press release.

In an interview with NatGeo News reporter Richard A. Lovett, lead researcher Franck Marchis, a planetary astronomer at the University of California, Berkeley, and the SETI Institute, said of the new image: “We have something comparable to or even better than the Hubble Space Telescope.”

Wow. But this isn’t the first time researchers using ground-based ‘scopes have compared their work to products of the aging but much beloved Hubble.

When it launched in 1990, the orbiting telescope was quite a coup for astronomy, because even the most powerful lenses on Earth tended to get blurry images of objects thanks to the same turbulence in the planet’s atmosphere that makes stars twinkle poetically.

In Jupiter’s case, the new image used a computer-assisted technique called Multi-Conjugate Adaptive Optics Demonstrator, or MAD.

The process involves correcting distortions by comparing them to shifts in so-called guide stars, ones with precisely known locations. Using many guide stars allowed the MAD team to remove blur from a field of view 30-times larger than any previous effort, so that the new image shows details as small as 180 miles (300 kilometers) across.

But how sharp is sharp enough, and will Earthly observatories ever surpass orbiters and other space probes for level of detail?

Cost is certainly an issue, as Hubble has shown that getting a ‘scope into space and then keeping it running can come with a hefty price tag.

If we can do the same looking for less moolah, that’s government dollars that could be funneled to other parts of science, which, even when recession isn’t looming, often feels like the least favorite player in any game of fund-my-project (ahem, bear DNA).

Right now I kinda feel like no matter how many guide stars you have, there’s always going to be room in astronomy for sending a robot—or maybe a human—into space for exploration purposes, even if it’s just to take a few in-person family portraits.

Featured Research: Mushara Elephant Project

Caitlin O'Connell and her husband, Tim Rodwell, started the Mushara Elephant Project in Namibia 24 years ago to better understand elephant social structure, communication and health in order to apply this knowledge to improved care in captivity and ultimately to elephant conservation in the wild. O’Connell is on the faculty at Stanford University School of Medicine and CEO of the elephant-focused nonprofit, Utopia Scientific. A grantee of the National Geographic Society, she is also an award-winning author of six books about elephants. Read Caitlin's dispatches from Mushara.

Nat Geo Expedition: Rising Star

Two years after being discovered deep in a South African cave, the 1,500 fossils excavated during the Rising Star Expedition have been identified as belonging to a previously unknown early human relative that National Geographic Explorer-in-Residence Lee Berger and team have named Homo naledi.

With at least 15 individuals of all ages and both sexes represented, the find adds an unprecedented amount of information to our understanding of early human evolution in Africa.

In addition, the absence of any other animal remains or large debris in the fossil chamber strongly suggests that these non-human beings intentionally deposited their dead within this cave.
